Solve quadratic equations
ax² + bx + c = 0
Quadratic Formula
x = (-b ± √(b² - 4ac)) / 2a
The quadratic formula solves equations of the form ax² + bx + c = 0, where a ≠ 0. The discriminant (b² - 4ac) determines the nature of the roots:
- Positive: Two distinct real roots
- Zero: One repeated real root
- Negative: Two complex roots
